COTTON GIN.

Application led December 17, 1918. Serial No. 267,108.

To all to/0m t may concern:

Be it known that I, JOHN lVooLnmnGn, a citizen of the United States, residing-at Temple, in the county of Bell and State of Texas, have invented a new and useful Cotton Gin, of which the following is a specication.

This invention relates to cotton gins of the double type wherein seeds, after being acted on by one set of saws, are delivered, with the adhering lint, to another set of saws where practically all remaining lint is removed. In gins of this character effective operation has often been impossible because the seeds and lint have clung to the first set of saws too long and seeds and lint have not been supplied in suiic-ient quantities and with desired regularity to the second saws. have been discharged from the first set of saws with the seeds to the saws of the second set.

One of the objects of the present invention is to provide means whereby the seeds are cleared from the saws automatically and all of the cotton in each roll box is fed against the saw teeth, thereby preventing tlie escape of locks of cotton with the seeds.

lith the foregoing and other objects in view the invention consists of certain novel details of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claim it being understood that various changes may be made in the construction and arrangement of the parts without departing from the spirit or sacrificing any of the advantages of the invention as set forth in the appended claim.

In the accompanying drawing, which is a. vertical section through the improved'gin, the preferred form of the invention has been shown.

Referring to the. figures by characters of reference, 1 designates the upper roll box of the gin under which the saws 2 are'arranged as ordinarily. The ribs 8 incline downwardly to a delivery hopper l and the front board of the roll box is hingedly mounted y at its upper end, as shown at 6 while its lower end projects into the upper portion of said hopper where it is connected to a rod 7. This rod is slidably mounted in a guide 8 having a tubular` stem 9 on which an adjusting nut 10 is mounted. A spring 11 is mounted Furthermore whole looks of cotton' on the rod 7 and bears at one end against trie-nut 10 so as to press the board 5 yield- Specification of Letters Patent.

ingly toward the saws 2. Within the hopper I Zlis journaled a roll 12 having radial lingers 18 projecting therefrom and between the saws 2*.

rlFhe hopper 4 discharges into the lower roll box 1 4: of the lower saws 15 andthisl roll box is provided with a hinged frontv board normally pressed inwardly toward the saws by a spring controlled stem 17 similar to the stem 7 hereinbefore described. Dof-A ng brushes 18 are provided' for the two sets of saws and operate to deliver cotton to the flue 19. v

When cottonis supplied to the box 1 the board 5 will shift outwardlyy under `the pressure `of the cotton roll thereagainst and will, at the same time, lpress the roll against the saws so that locks of cotton cannot escape past the saws and into the hopper 4. rIhe pressure of the cotton on the fingers 13 saws and thus clear the cotton and seeds from the saw teeth and insure the uniform feed of material through hopper-4 to the lower vwill cause said fingers to move between the v roll box. Here the board 16 `also,acts to i press the material against the saws 15 so thapractically all lint is removed fromv the seec s. ginning operation is greatly increased because loss of lint is reduced to the minimum. `What is claimed iszV In a gin, a roll boX having a downwardly curved upwardly and outwardly opening hinged front board, a hopper arranged below said box into the upper end of which the free end of said board projects, ribs constituting one wall of said hopper, gin saws Xtending between said ribs into saidhopper and into said roll box, a rotatable roll in said hopper having fingers extending be- J.
